General Merchant on the Nexus keeps ripping me off

Are they supposed to show up in your cabin?

Go to the loadout locker next to the bridge (or starting a mission or at a forward station) and it should show up on the last tab with the Nomad icon.

I can see them in my inventory under resources > special items but I can't sell them. They've also decided to appear in my cabin alongside the Normandy just now. Unless the bug is actually where they disappear after a while?

This happened to me with the Nomad skins! I bought them all, but none were in my inventory at all! I kept going back and checking and they never showed up again. But then theblack one showed up, I bought that and it was in my loadout selection... And now so is the indigo one or whatever... But those first few are just gone.

I started a new game plus, and i had the items for movie night in my Inventory, so the quest with Lexi triggered right as i got the Tempest. So had to reload and now i can't talk to Lexi! Think i'll wait for a few patches.

Are you able to remove those items, or do they at least disappear when the quest is completed? 

Easy now...  I don't live there, I just visit occasionally!

Is that the same merchant who keeps magically popping in and out on the screen?

Yeah happened to me too. It's a minor thing but should be patched someday nonetheless.

Same problem.

I've got empty shelves.

Its like the bug for those dwarven tiles in DA:I that they never fixed.

I saved the moshae and found Jaal in the kitchen. Was teleported to the inside of his room with the door locked and when I tried to leave it triggered the cut scene for when you kill Aksuul.

Then the one about his mothers worrying for his cousins.

Now theres no door to that room anymore.

Made it out that loop and now I'm scared to talk to anyone.

I hear you, the Tempest plays with time and space.  Sometimes the door to PB's room literally opens to nothing but space. I can even see the stars and colors of the system the ship's in at the moment!

But yeah, I had the same bug as you once and escaped it fine by reloading. It was actually also with Jaal. I think it's due to squadmates roaming but having spot specific cutscenes. Basically, there's a chance that you'll talk to a squadmate and start this spot specific cutscene while said squadmate is not at the spot the cutscene is supposed to play in. As a result, it seems the game tries to simultaneously play the cutscene while trying to move you and the squadmate to the correct location. It create issues during and after the scene but like I said, it seems fixed after reloading so that's thankfully a relief.

The above issue with PB's room is probably textures being slow to load but whether that's my computer or the game, I don't know. Regardless, it cracks me up because I also run towards it before noticing it so I can't help but imagine my character coming to a sudden halt as she notices the door is missing.
